The film revolves around the true story of Ron Stallworth (John David Washington, Denzel’s son), a black Colorado Springs cop who infiltrated the Ku Klux Klan in the ’70s. Adam Driver, Topher Grace and Laura Harrier also star in the film, slated for an August release in the U.S.

A montage about last summer’s racial clash in Charlottesville, Virginia, ends the movie, providing a bookend to a Cannes day in which race ― and Lee ― dominated the conversation.

Lee included a dedication in the film to Heather Heyer, who was killed in Charlottesville by a man driving his car into people protesting white nationalism.

Lee used that as a jumping-off point in a fiery condemnation of Trump at an earlier press conference.

“That motherfucker was given the chance to say we are about love, not hate,” Lee said in the clip below. “And that motherfucker did not denounce the motherfucking Klan, the alt-right, and those Nazis motherfuckers. It was a defining moment, and he could have said to the world ‘not the United States,’ that we were better than that.”
